Y CAP FOB GREASEl AND LU'BBICANT CUPS.

-To allftplzfofmzmayconcern.` f I Be ait-known that I, Groen W. BOWEN, of Auburn, fin the county ofQayuga and State MNew Kork', vhave invented certain new anduseful Caps for Grease andLubricant. ps, of which the following a specifica- I My invention relates to greaseand lubricant cups, and; particularlto caps or closures therefor, and the ob]ect ofl the inven-v tion is to provide avcap or closure which 1 A tion of the cap,showing clearly the internal formation thereof. Fig. 4 is a view in elevation of another form vof grease cup comprisinga cap slightly different from that shown in Figs. 1', 2 and 3,.but embodying myinvention.

. Referring to the drawings-I would state, before entering in to a detailed description *of my present invention, .that the same is' shown as being employed in connection with the body of a grease cup made from a blank' sheet of metal,- 'the said body vbeing a separateiiiivention'covered by my pending application, SerialNd 246,84r filed Feb# ruary 23, 1905; Brieiydescribed, this body 40 consists of a conical or funnel-shaped part 1, from the upper edge of which rises an integral cylindrical wall 2, provided ,prefers abl with external threads 3. Merging with an projectig `from the apex. or outleto the funnel-s aped part 1, isa stem 4, coaxial with said part 1 and formed at an intermediate portion with 'circu'mferentially arrang'ed angular faces '5, adapted to beengaged by a wrench, the lower end of said stein forming an attaching-nipple by means of which the grease cup may be applied in operativerelation to a part to be lubricated. As above stated, the construction described Y"formsthe subject-'matter of a separate apl ASpecicatioii of ettei's .tatent.-

iof' this application. uid state atthis point, that while .thecapembodying ,my Zpresent invention is'shown. as described in connection with thebody just referred to,' Il

desire it understood that it'may be em- ;ployed with any grease cup body orirecep'- :tacle ofthe same generali e,oi so conistructed -that my cap mayydb there'to. The cap referre'djembodiment of my invention-"is ormed from a tubular orhollow body 'of sheet" metal, and consists of' acylindrical. body portion and a head portion, both hav-f e applicable iportion 6. is open atffits lower endandjs illustrated 'iii the'rawingsfas ,ai

-g ing an .unbroken outer..k surface.- Iliefbody v provided with.' internal' threads 7 adapted to2 engage thetlireads 3' on the wall/2 of, thefl body or:1 the 'grease clip. The head portionv of' the' cap consist'sQof segmental lp having their curved -e'dges integral with, and merging linto the side wall of.\thel body, and a perpendiculapat 9 comprising su'bst'am"` tiuallyu parallel segmentalportions 9* merging at their' bases into the contiguous por-l tions of the parts 8, and having their curved edges integral with each other, opposite ends integral with, and merging into, the side wall of the body at diametriarts 17B:

land their cally opposite portions thereof. Preferably, Y

the upper parts of the innerfaces of the substantially parallel segmental portions` 9 comprising the perpendicular part 9 'are substantially in contact with each other, Fig. 3,

to brace each other `and lend strengthrand parts of said portions? divergetowa contiguous portions of the segmental! arts 8. The part 9 of the head portion' o 'theY cap is adapted vto be engaged by the fingers of the operator, or a suitable toolwhen the cap is being applied in, or removed from, operative osition. L,

In pro ucing the cap described from a and the lower or inner rd the .cup shaped blank, or tubular body pressed 'from a suitable sheet vmetalblank, opposite portions of the wall Aof said cap,or tubular 'body may be flexed inwardly'toward each other to form the head portion ofthe'cap and the projecting part 9 thereof In Figsl to 3 of thedrawings, I have' :shown the invention as applied `to a grease cup of the. force-feed tylpe, lin which the cap is designed t o be co afp'sed upon the body of the grease pup to i orce the lubri- -5-5 plcation, and -o'r' this reasontliebrief ydescription given will suce'forthepurposes cant from the` opening 'inthefstem of the iio body, this operation being accomplished by .i

screwing the cap down upon said-body.

In Fig. 4, I have shown the invention applied to a cap for another type of grease cup, in which the cap serves merely as av closure for the cup. In this adaptation of the invention, 10 designates the body 'of the grease cuphthe closure therefor consisting v-formation as that shown in Figs. 1 tov3 of the drawings. Y

' What I claim, is:- 1. A one piece sheet metal cup shaped ,l cap comprising a cylindrical body portion anda head portion having an unbroken outer surface, said headlportion consistin of segmental. parts 8 having their curve edges integral with, and merging into, the side wall of the body, and a perpendicular part 9 comprising substantially parallel segmental portions merging at their bases into the contiguous portions of the parts 8, and having their curved edges integral with each other, and their .opposite ends integral with, y: and merging into, the side Wall .of the body l at diametrically opposite portions thereof.

V2. VA one piece sheet metal grease cup cap having an unbroken outer surface and comprising a cylindrical yinternally threaded body portion, and a head portion consisting of segmental parts 8 having their curved edges merging into the side wall of -the body, and a perpendicular part 9 comprising substantially parallel segmental portions` .having 'parts of their inner faces substantially vin contact with each other and other parte thereof adjacent the parts 8 diverging toward the latter, the said substantially parallel portions being integral with, and merging into, the contiguous portionsof the parts I 8 andI having their curved edges formed in-- tegral, with eachother, and'tlieir opposite ends formed integral with, and merging into, the side Wall of the bod at diametrif callyv opposite portions theieo In testimony-whereof, I have hereunto rsigned my name in the presence of tyvo attesting witnesses, at Syracuse, in the county of Onondaga, in the State of New York,
